Development And Application Of Self-made Teaching Aids For Physical Optics In Middle Schools

The experiment-based middle school physics classroom needs certain material conditions as support,and self-made teaching aids are important physics curriculum resources.In order to fill the vacancy of some experimental equipment,stimulate students’ interest in learning physics,improve the effect of physics classroom teaching,and promote the comprehensive ability of teachers to develop and apply self-made teaching aids,the following researches are carried out on the development and application of self-made teaching aids for physical optics in middle schools:(1)Sort out the research background of self-made teaching aids,expound the research significance,and determine that the research content of this thesis is the development and application of self-made teaching aids for physical optics in middle schools.The research methods adopted are literature review,questionnaire survey,interview and case analysis.(2)Using the literature review method to sort out the research status of Chinese physics curriculum resources,physics experiments,self-made teaching aids,and optics teaching,it is concluded that the number of studies on middle school physics curriculum resources and physics experiments is large and involves a wide range;The research history of this thesis has a long history,but it is not systematic and imperfect;there is a large demand for self-made teaching aids in the content of physical optics in middle schools,but there are few related researches.(3)Define the core concepts of teaching aids and self-made teaching aids.Selecting constructivist learning theory,"learning by doing" theory,meaningful learning theory,and information processing theory as the theoretical basis of this research,combined with the requirements of middle school physics curriculum standards,it analyzes the processing of optics in middle school textbooks.(4)Preliminary analysis of physics experiments and self-made teaching aids by questionnaire method and interview method.It is found that: at present,students have demand and love for self-made teaching aids,but the application of self-made teaching aids in middle school physics classrooms is not optimistic.Teachers develop self-made teaching aids independently.situation is minimal.In view of the existing problems,a preliminary cause analysis was made.(5)Under the guidance of theory,combined with the personal experience of actual production of teaching aids,referring to the research results of predecessors,the development principles and development strategies of optical self-made teaching aids are introduced,and the application strategies of optical self-made teaching aids are summarized: rational use of teaching aids,Highlight the value of education;encourage students to participate and improve teaching efficiency;combine modern technology to optimize experimental results;attach importance to one tool for multiple uses and realize the systematization of teaching aids.(6)The specific development and application cases of six self-made physical optics teaching aids in middle schools are given,namely: plane mirror imaging demonstrator,space-time tunnel,polychromatic turntable,total reflection teaching aids,light diffraction experimental teaching aids,and multifunctional optical demonstrator.Each one introduces the development process of teaching aids from the background and intention of production,production method,usage method and experimental effect.Then discuss its application in actual teaching,and finally analyze and demonstrate the innovation points and application effects of teaching aids(students’ classroom performance,after-class feedback,peer evaluation,etc.),and finally summarize the entire case from the two dimensions of teaching aids and teaching.Reflect.The common features of these cases are mainly manifested in: simple production,low cost,convenient operation;obvious experimental effect,intuitive,easy to observe;good effect in classroom,popular with students;able to visualize abstract physical knowledge,improve The effect of physics teaching;it can stimulate students’ interest in learning,and is conducive to promoting the cultivation and development of students’ core literacy.(7)Finally,the conclusion of this study is willing to provide reference for teachers and students.The innovations of this study are:(1)A series of optical self-made teaching aids with good effects have been developed;(2)The developed results have been used in teaching practice,and the rich educational functions and teaching values have been tested;(3)Innovative in the development of teaching aids The use of modern information technology has improved the experimental effect.
